(Reader, and Canada's own, Blair Buchta recently pointed out in an email that "Israelites" by Desmond Dekker & the Aces was one of the first reggae hits to reach the top 10, rising to No. 9 in 1969.)

Canada can: The ascent of "Rude" to No. 1 marks the first time in more than 12 years that a Canadian band (all four members of MAGIC! are from the Toronto area) has topped the Hot 100. Nickelback began a four-week command with "How You Remind Me" the week of Dec. 22, 2001.

Other Canadian bands to control the Hot 100: Barenaked Ladies ("One Week," 1998), Sheriff ("When I'm With You," 1989), Bachman-Turner Overdrive ("You Ain't Seen Nothing Yet," 1974) and the Guess Who (the Stateside-themed "American Woman").

Nasri No. 1: MAGIC! frontman Nasri Atweh joins his bandmates in their first visit to the Hot 100's summit, but he'd previously reached the top 10 as a co-writer on three songs. Fellow Canadian Justin Bieber's "Never Say Never" reached No. 8 in 2011 (featuring Jaden Smith) and "As Long as You Love Me" (featuring Big Sean) climbed to No. 6 in 2012. Atweh scored his third top 10 writing credit when Pitbull's "Feel This Moment" rose to No. 8 last year. Atweh made his Hot 100 debut as a writer on New Kids on the Block's "Summertime," which reached No. 36 in 2008.Oh, oh, it's 'Magic': "Magic" becomes the first word to serve as the title of a No. 1 Hot 100 song and an act with a Hot 100 leader (excluding the exclamation point at the end of the band's name …) Olivia Newton-John spent four weeks at No. 1 in 1980 with her song "Magic." (Reader Jeff Lerner first pointed out the potential doubling up in last week's "Ask Billboard" reader mailbag. Honorable mention to Mariah Carey's "Emotions" and the group The Emotions, whose "Best of My Love" led for five weeks at No. 1 in 1977.)

'Rude'-ness rewarded: Of the approximately 26,000 songs ever to hit the Hot 100, only two have included the word "rude" in their titles … and both have reached No. 1. Rihanna's "Rude Boy" charged to No. 1 for five weeks in 2010.

(Just one such act has hit the Hot 100, and "rude" was its middle name: The Rude Boys' "Written All Over Your Face" peaked at No. 16. Starting the trend of "rude" hits scoring chart success, the song topped Hot R&B/Hip-Hop Songs for a week in 1991 and won the Billboard Music Award for No. 1 R&B single that year.)

How did "Rude" rise to the top of the Hot 100? It rebounds 2-1 (after two weeks at No. 2) for a second week atop Digital Songs with 185,000 downloads sold (up 3 percent) in the week ending July 13, according to Nielsen SoundScan. It pushes 4-2 on Radio Songs with a 9 percent surge to 152 million all-format audience impressions and lifts 3-2 on Streaming Songs, up by 8 percent to 8.3 million U.S. streams, according to Nielsen BDS. "Rude" concurrently crowns the subscription services-based On-Demand Songs chart, climbing 2-1 (3.3 million on-demand streams, up 8 percent).

"Rude" narrowly takes over the Hot 100's top spot: it gains by 2 percent in overall points, while "Fancy" decreases by 5 percent. "Rude," thus, wins the race to No. 1 by a mere 1 percent points margin. Last week, "Fancy" held a 6 percent advantage over "Rude."

Now, where were we before we were so "Rude"-ly interrupted?

Ah, Iggy Azalea. "Fancy" falls to No. 2 on the Hot 100, although it leads Streaming Songs a ninth week (10.6 million, down 1 percent). It dips 3-4 on both Radio Songs (138 million, down 5 percent) and Digital Songs (154,000, down 10 percent); it led the lists for three and four weeks, respectively. Meanwhile, "Fancy" tops Hot R&B/Hip-Hop Songs for an eighth week and Hot Rap Songs for a 13th frame.

Despite their drop from the top, both Azalea and Charli XCX charge ahead on the Hot 100 with follow-up singles. Azalea's "Black Widow," featuring Rita Ora, vaults 97-65 as the chart's top Digital Gainer (41,000, up 118 percent), while Charli XCX's "Boom Clap" climbs 20-16, led by a 10-8 lift on Digital Songs (100,000, up 3 percent).

Ariana Grande's "Problem," featuring Azalea, holds at No. 3 on the Hot 100 for a third week after peaking at No. 2 for five weeks, while Nico & Vinz's "Am I Wrong" is stationary at its No. 4 peak to date. The latter leads Radio Songs for a second week (160 million, up 6 percent) and, as previously reported, rises 2-1 on Pop Songs and rules Adult Pop Songs for a third week.

Sam Smith stays at his No. 5 highpoint on the Hot 100 with "Stay With Me," which adds top Airplay Gainer honors. It bullets at No. 5 on Radio Songs for a second week with a 13 percent increase to 125 million. On Streaming Songs, it soars 24-15 (3.5 million, up 27 percent).

Jason Derulo's "Wiggle," featuring Snoop Dogg, is a non-mover at No. 6 on the Hot 100 and John Legend's former three-week No. 1 "All of Me" reverses course (8-7).

Maroon 5's "Maps" moves 9-8 on the Hot 100, highlighted by a 9-7 push on Digital Songs (105,000, up 1 percent) and a 12-9 ascent on Radio Songs (65 million, up 11 percent). The band tallies its ninth Radio Songs top 10, tying TLC for the second best total among groups. Destiny's Child leads all groups with 10 Radio Songs top 10s dating to the chart's December 1990 launch.

Calvin Harris' "Summer" slips from its No. 7 Hot 100 high to No. 9. Still, it dominates the Hot Dance/Electronic Songs chart for a fourth week.

Smith, meanwhile, scores his second Hot 100 top 10, as Disclosure's "Latch," on which he's the featured vocalist, rises 11-10. With airplay accounting for the majority (45 percent) of its chart points, it holds at No. 8 on Radio Songs (85 million, up 7 percent) and No. 11 on Digital Songs (82,000, down 9 percent), while rising 27-26 on Streaming Songs (2.8 million, up 5 percent).

"We thought 'Latch' was too weird for the radio and not clubby enough for the clubs," the duo's Guy Lawrence revealed in the July 5 Billboard cover story. (Younger brother Howard rounds out the pair.) "It's in 6/8 time, not even 4/4, which is house's tempo.

"'Latch' is just … a strange song that people like."
